Note: For information on removing the server cover, see “Removing
the Cover” on page 49.
To access the section of the system board you need to work with,
you might need to remove adapters or the riser card. Also, you
might need to remove cables that are attached to the system board.
When disconnecting cables, it is important to note where they

The following examples describe when you might need to remove
components:
